Abstract

El desfasaje en un medidor electronico de energía es compensado obteniendo lecturas de temperatura y de frecuencia en el medidor y utilizando esta lectura en un procesador de senales digitales (DSP) dispuesto dentro del medidor electronico de ingeniería. La compensacion por frecuencia y temperatura se efectua en cada calibracion de fase y el resultado es almacenado en el DSP. Para reducir la posible influencia de ruido en la disposicion, los valores compensados del DSP son filtrados para proporcionar un emparejamiento de los datos.
